Challenge
The Hopple Street bridge above I-75 needed to be strengthened to an appropriate capacity. The project required complex traffic control and challenging access to heights.
Engineered Solution
Carbon fiber wrap was the chosen technology for structurally rehabilitating the existing bridge. The FRP technology increased the bridge’s shear strength.
Scope
The project required nightly lane closures and a hydraulic lift to access parts of the supporting structure that were up to 50 feet above the interstate. The surfaces were prepared by pressure washing and grinding. Multiple layers of carbon fiber were applied to specific pier cap sections in a continuous form. The process was completed in a two week period.
Solution
The application of fiber wrap reinforcement restored the integrity of the Hopple Street bridge. It proved to be a flexible solution that allowed mobilization and demobilization, affecting traffic only at night on this congested section of the interstate. The project was completed in a fraction of the time and at a fraction of the cost required by other repair and reinforcement methods.
